These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Big Lipped Alligator Moment: In the first game, using the Chibi-Radar in the living room will turn up a "dig spot" in the carpet. Dig and a little fat blue man in a purple speedo with a spark plug for a head will pop out, and continuing to jab him with the spoon will cause him to dance in place and grow to five times his size before awarding you Happy Points and vanishing. "Mr. Prongs" doesn't do a thing in the main plot or come up at all in between any other times you might look for him again for the points.
Also, just what the hell were those little portals in the wall? You open a "Chibi-Door," and you're suddenly in a tiny room with Mushroom Samba background and music.
